TEMPUH-AHY BINDER.

SE'ECIFICATIQN forming part of Letterslatent No. 764,266, dated July 5, 1904.

Application filed May 14, 1903- To all whom it mntyconeern:

Be it known that I, Josnrn W. AMRATH, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Temporary Bind ers, of which the following is a specification.

My invention relates to temporary binders, but is intended more particularly for use as a transfer-file for keeping in proper order and sequence the leaves or cards which form the fillings of so-ealled loose-leaf ledgers.

The object of my invention is to furnish a cheap, simple, and convenient device'for receiving and retaining for as longas may be desired these cards or leaves transferred from a ledger.

A practical embodiment of my invention is shown in the accompanying drawings, in which Figure 1 is a side elevation of the complete device in its locked position. Fig. 2 is a plan view with the upper plate of the guide-frame removed. Fig. 3 is a cross-section on line a a; of Fig. 2. Fig. i is a eross-secti'on'on line y y of Fig. 2.

1 represents a base-plate, in which are se cured any suitable number of vertical rods 2, two of which are shown in the drawings. Fitted upon these screws is a clamp, which is adapted to be pressed down upon the leaves or cards strung upon the screw-rods. The clamp can be entirely removed fronuthe rods, so that if the leaves-have perforations within their edges such leaves can be threaded upon the rods vat'ter the clamp has been taken ed. in many loosedeat' ledgers, however,ti'1e leaves are provided with key-shaped slots producing the eiiiect of interior perforations, which are open to an edge of the card by means of relatively narrow passages. Cards like these can be fitted to the holding-rods by a sidewise movement, making it unnecessary to remove the clamp. When the desired number of cards are in place, the clamp is pressed down upon them and is locked to the said rods. The clamp is composed of two members 3 t, which may be separate strips of metal or, as shown in the drawings, may be a single strip bent upon itself and having its free ends remov florial No. 167,128. (No modal.)

ably secured together by a distance-piece 5. The parallel members 3 a form a guide,in which the lockingdevice'is movable. The rods 2 pass through the clamp at one side otits cam-shaft 6, which is journaled in the ends of the clamp and may also be cut away, as shown at 7, to bear within slots in the intermediate distance-pieces 8. The end of the cam-shaft projects beyond the clamp. and is provided with a handle 9. It has no longitudinal move ment, but can be turned in either direction, so'as to bring the cam-faces 10 against the rods 2 or to withdraw themfrom such contact. In the former case the clamp is looked upon the rods at any distance from the base;

it to be pressed down upon the leaves and then looked. I have shown three sections of camfaces in the drawings and two guide-rods; but it will be understood that as many guides and the size of the leaves. that the rods are smooth-surfaced and not threaded, so that there is no interference with the free sliding adjustment of the clamp, the latter being rigid and preventing any binding action. v

I prefer to make the guide-rods 2 in several sections, as shown, in order to increase the capacity of the his for holding leaves as great as may be necessary. Each section is provided at one end with a screw-threaded stub end fitting a screw-thread ed socket in the being closed by a cap 12, which fits all the end sockets. Each section may also have a hole 13jto receive a turning-pin. I thus provide extensible and contractible smooth-surfaced rods, which can be locked by the cam-shaft at any point in their length.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. A temporary binder comprising a plate, guide-rods secured therein, a clamp adjustable upon said rodsand a cam-shaft journaled longitudinally in the clamp and adapted to be turned in both directions so as to bear upon middle line, leaving room for the longitudinal,

but in the latter event it is released and can, be moved freely on the guide-rods, enabling cams can be provided as may be required by it will be observed end of the adjacent section, the last section and lock said clamp to the rods, or to release said clamp from the rods.

2. A temporary binder comprising a plate, guide-rods secured therein a clamp having two parallel plates, through both of-which such rods pass, a shaft journaled between said plates and cam-faces on said shaftv adapted to bear upon said rods and thereby lock said clamp.

,3. A temporary binder comprising a base, vertical guide-rods secured thereto, a clamp adjustable on said rods, a horizontal shaft
